Posts claiming that US President Joe Biden has been replaced by another person, arguing that his eye color has changed with age, are false.

Some posts include an image made up of two separate photos of President Biden with the caption: "Something just doesn't look right... because it's not. PS Eyes don't normally change color with age."
Comments on the posts include: “We are living in Hollywood blockbuster movies!!!! You can’t tell who is who!!! You can’t tell what is real!!!”, “Clone/body double for sure. The real Biden has been executed” and “it’s the eye color that scares me… I don’t think our eyes change color as we age…”
Claims that Biden was executed or replaced appear to be tied to the widely debunked QAnon conspiracy theory. Some QAnon supporters, who claim that former President Trump was secretly fighting child sexual abuse predators, include prominent Democrats, Hollywood elites and “deep state” allies (here), have claimed that Biden is not actually president and that the military is in power until Trump returns to office.
On the left of the image is a photo of Biden at a younger age, in 2006.
The photos to the right of the image in the posts come from a screenshot of Biden's presidential campaign announcement video from April 25, 2020, visible on C-SPAN. Although his eyes appear darker in some parts of the video, their color is still noticeable as blue.

Recent photos of Biden taken by Reuters as well as his presidential portrait (here) show that his eyes still look blue.

Eye color remains largely constant throughout a person's life and may appear to change due to illusions in the lighting and colors around the person. Eye color can sometimes change with aging, or due to a medical condition or trauma (further reading can be found here, here and here).
Reuters Fact Check had previously debunked a similar claim that Biden's eyes appeared black during the first presidential debate.
